Calculate the LCM of 768,788,426,426

Given numbers are 768,788,426,426

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 768,788,426,426 is 10742016.

Find LCM of 768,788,426,426 with Prime Factorization


2 768, 788, 426, 426
2 384, 394, 213, 213
3 192, 197, 213, 213
71 64, 197, 71, 71
64, 197, 1, 1

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 71 x 64 x 197 x 1 x 1 = 10742016

Therefore, the lowest common multiple of 768,788,426,426 is 10742016.

LCM Formula to Find Lowest Common Multiple of 768,788,426,426

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

768 x 788 x 426 x 426 = 109826371584

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

788 : 1, 2, 4, 197, 394, 788

426 : 1, 2, 3, 6, 71, 142, 213, 426

426 : 1, 2, 3, 6, 71, 142, 213, 426

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 768,788,426,426, is 2.

Now, the common factors can be found like this.

768:2x 2x 2x 2x 2x 2x 2x 2x 3

788:2x 2x 197

426:2x 3x 71

426:2x 3x 71

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3x 3x 71 = 5112

Therefore, the value for common factors is 5112.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 109826371584/(2x5112)

LCM = 109826371584/10224

LCM = 10742016

Thus, we can understand that the LCM of 768,788,426,426 is 10742016.
